Title

All RHEL 9 local initialization files must have mode 0740 or less permissive. (Cat II impact)

Discussion

Local initialization files are used to configure the user's shell environment upon logon. Malicious modification of these files could compromise accounts upon logon.

Check Content

Verify that all local initialization files have a mode of "0740" or less permissive with the following command: Note: The example will be for the "wadea" user, who has a home directory of "/home/wadea". $ sudo ls -al /home/wadea/.[^.]* | more -rwxr-xr-x 1 wadea users 896 Mar 10 2011 .profile -rwxr-xr-x 1 wadea users 497 Jan 6 2007 .login -rwxr-xr-x 1 wadea users 886 Jan 6 2007 .something If any local initialization files have a mode more permissive than "0740", this is a finding.

Fix Text

Set the mode of the local initialization files to "0740" with the following command: Note: The example will be for the wadea user, who has a home directory of "/home/wadea". $ sudo chmod 0740 /home/wadea/.<INIT_FILE>
